One thing LF can really make you do is do your best to make every exposure count. A pocket/pouch on a bag can hold easily hold a couple hundred frames worth of 35mm or 100+ frames of 120(even shooting 6x7). I don't think I've ever gone out with more than 5 4x5 film holders(10 frames) and that's an unusually high number for me. Usually it's 2 or 3 holders, and I might only shoot one of them. Of course, that's part of the beauty of it too. I know with 35mm especially, I've been known to shove some crap onto the end of a roll just so I could finish it and develop it. That's less of a problem with 10 or 12 exposures in 120. If I go out with 4x5 and only shoot one frame, no problem, I just strip that sheet out of the holder and develop it.
